Here's the Real Reason Why a Major 'Thor' Character Isn't in 'Ragnarok'

In Marvel’s Thor: Ragnarok, the apocalypse looms large over Asgard, prompting Thor to fight the resurrected Goddess of Death, Hela. But of all the major Marvel Cinematic Universe heroes to return and save Asgard, one major ally of Thor is conspicuously absent throughout the entire movie. And in a new interview, we finally know why.

While Thor’s allies, the Warriors Three, do appear in Thor: Ragnarok after all, the mighty Lady Sif, played by Jamie Alexander, is sorely missing. That’s because Alexander was occupied shooting the latest season of her popular action drama, Blindspot on NBC. “I was asked, but the timing of when they were going to shoot and when Blindspot was gonna shoot — it was pretty much the same time,” Alexander said in an interview with Yahoo last Friday. “So there was a conflict there.”

Alexander explained that Marvel Studios didn’t give her enough heads up to work out the scheduling. “I was hoping for more of a notice from [Marvel] so I could make it work, but it was a short notice thing. They called and said, ‘Hey, by the way, would you come do this?’ I said there is no way I can make that work that fast.”

For a while, it seemed all but definite that Alexander would reprise her MCU role as Lady Sif in Thor: Ragnarok, and that the Warrior’s Three — Fandral (Zachary Levi), Hogun (Tadanobu Asano), and Volstagg (Ray Stevenson) — would be the ones left out of the movie. Turns out, it was the complete opposite.
